Any photo or link you share has your digital fingerprints. Digital items have metadata. Metadata provides information about other data. It is “data about data.” It can give information where, when, and which unique device the data was from, so that anonymous email you sent from the yahoo account you just made, was not so anonymous.
The particular metadata that should be of concern regarding photos is the Exchangeable Image File Format (Exif) tag.
From Consumer Reports:
“Details about when, where, and how a photo was taken are captured automatically by smartphones and digital cameras, and stored as Exif (Exchangeable Image File Format) data. Information on everything from exposure settings to altitude may be included. And the Exif data travels with the photo—from the camera to your hard drive or a website.”
Millionaire John McAfee formerly the King of Antivirus, currently self-described as Crypto Jesus, was a person of interest in his neighbor’s shooting death. His location was unknown, until he did a Vice interview.
From Naked Security:
Twitter user @simplenomad noticed that a picture published today by Vice Magazine, contained some information that John McAfee might have preferred remained secret.
But also be aware.
Don’t make it easy by being human.
